TAPER-GAUGING MACHINE.

Application filed August 4, 1926. Serial No. 127,060.

My inventiony relates to taper vga-ugi'ng machines and has for its principal object a simple and accurate means for automatica-lly gauging theftaper of such articles as taper rolls for roller bearings. The invention consists in a taper gauging device that can be incorporated in a.- inachine for gauging the sizes of such rolls. The invention consists principally in an adjustable housing in which mountedl a taper gauging mechanism that is able to accommodate itself to different sizes of rolls. The invention further consists in the gaugin'gmachine and in the parts and combinations of Aparts here inatter described andI claimed.

in the accompanyingl drawing, wherein like numerals indicate like parts wherever they occur, y A

1 is a top plan view of a gauging machine embodying my invention,

Fig. 2 is a part vertical sectional view thereof,

Fig. 23 is a cross sectional viewl on the line 3 3 in Fig. 2,

Fig. f1 is a cross sectional view on the line 1-41 in Fig. 9,

Fig. 5 is an end elevation; and

Fig. (i is a vertical sectional view on the line 6MB in Fig. 2.

A housing 1 is orovided with a bore 2 whereby it mounted on an uliistanding-column 3 cna suitable base d. Extending through another bore in said housing 1 is a. rod that is provided with an enlarged end portion T having a knurled head 8 and with a shouldeiI 9 atithe lower end whereby it is held in the housinpl 1i. Said rod 6 Vhas a threaded lower end 1() fittingl in a threaded hole in the base 4l. Thus the housing 1 may be raised. or lowered by turning said rod C. Extending through an elongated siot 11 in said housing 1 into the column 3 is a locking screw 12' that is provided with an operating arm 13. Thusthe housing 1 may be held in any desired position onn the column 3 by turnii'ig said locking screw 12 to clamp the housing 1 on the column 3. y

The housing` 1 is provided with an enn larged bore 11i parallel with the column 3, in which bore 'lef is slidably mounted a. hollow casing or slide 15 that is normally held in its lowermost position in the housing vby means of springs 16 secured to the enlarged tact springs 38 normally rest4 against said head 17 ofthe casing 15 and to the housing 1. A pin 18 projects from the housing into a slot 19 provided therefor in said casing or slide, so as to prevent rotary movement ofthe sli-de. Said slide 15 carries, the gang`- ing mechanism hereinafter described; and since said slide is yieldable in the housing` as above described, it can accommodate itselit' to different sizes of'work.

Mounted s o as to rock on a pin 2O ii, the slide is a gauging block 21 that is provided with. an upwardly extending projection 22. in whose top is forme-d ai if-shaped recessv 23.' In this recess 23 rests a knife .edge 24 formed in the Vmiddle of the lower `surface of a rock shaft 25.

The outer ends of the upper surface of said rock shaft 25 are provided. with alinedv knife edges 26 each of which ls received in an inverted V- shaped depressionv 27 formed in a block 28 that is fastened at the end to a flat spring 29. Said springs Q9 are secured to a bracket 30 as by .screws 31, which bracket 30 is secured` to thev slide 15 as hereinafter described. the construction just described, the rock shaft'Q- is held between the gauging block 251 and said hold-down blocks 28. 'A Contact arm 32 extending through said hollow slide 15 is provided with forked ends 33; that. are secured to said rock shaft 25, as by taper pins 34. Mounted on a cap 35 of vinsulating material in they upper end of the slide 15v is a. block 36 that isprovided with upstanding portions 37 to cach of which i-s secuned aA Contact member 38 of spring metal. vThe contact points 39 ofsaid contact members 38 are adapted to contact respectively with contact screws l0 mounted on a block 1l.A of electric conducting material secured to said cap 35 as by screws 452. The block 36 that carries said. Contact` springs 38 is connected to a battery or other source of electric current (not shownin the drawings), I f f y The upper end of the contact arm consists ofY a piny i3- of some non-conducting materiaL saidl pin extending between the ends of saidcontact springs interposed between said? Contact springs 38 near. their contact ends is a pin 14: ot non-conducting material that is of the same diameterasthe pin 43 of the contact arm 32 and is secured tothe block 411. Thus the ends of the conanchor pin il, and said contact si ings .'38 normally hold the pin i3 and contact arm l2 in neutral position', but when the gauging block 2l is tilted in either direction by an oth-taper roll` thc contact arm 2&2 will likewise be tilted and thel contact point fl ot one o'il the Contact springs 3c', caused. to contact with a contact screw il). "his will rcsult in the closingl oit an electric circuit and in the operation ol any suitable ejecting mechanism (not shown in the drawings) 'tor ejecting rolls that are oli-taper.

In order to permit adjustment ot the V- blocks 28 to place the rock sha'lt Q5 and contact arm 32 in Zero or nent al position the bracket 3() trom which said blocks 28 are supported is secured to a protecting` portion lo ot the slide, as by a screw =lG. :interposed between the inner surface ot the bracket 23() and said projecting portion i5 ot the slide l5 are springs et?. Said projecting` portion ot the slide l5 is shown as a separate inember, secured to the slide by screws d8.

,it suitable device -l-Q (which may be ci any well known construction and is' indicated diagramn atically, is provided tor moving` the taper rolls 5() along a suitable, track 5l or the like, to bring them, one at a time, under the gauging block 2l. it the roll 50 is o'if exactly the desired taper, there will be no movement of the gauging block 2lY or of the contact arm 32; but it the roll is oli taper, the gauging block will be tilted, thus rocking the rock shaft Q5 and causing the contact arm to be tilted. it the variation i'rom the correct taper is great enough, one of the contact springs 38 will be caused to contact with a contact screw 40, thus closingl an electric circuit and oiierating an ejecting mechanism. Obviously the limits ot tolerance may be varied by adjusting the positions ot' the contact screws i0.

The. device shows both sets ot contact screws #l0 and contact springs 38 connected up in a single ejecting circuit; but obviously two diii'erent circuits and ejecting devices might be provided, thus separating rolls having too much taper from those havingl too little taper.

The above described device may be incorporated in any of the well known types of machines for sorting taper rollers according to their size, the taper gauging' mechanism being made a station of the gauging machine operating prior to the tirst size gauge. The device is simple and easy to operate, there are few moving parts to get out of order and the device is very accurate. Obviously numerous changes might be made without departing from the invention and I do not wish to be limited. to the construction shown.
